Gardeners who grow cucumbers in a greenhouse often encounter a problem - the ovaries on the whips turn yellow, rot and fall off. Moreover, it all starts with the petals of the flower, then the rot goes to the ovary, and the process can no longer be stopped. To avoid this annoying nuisance, you need to know the causes of its occurrence and prevent them.

Bacteriosis

Bacteriosis is a common cause of ovary decay. Its spread along the cucumber ridge is facilitated by the increased humidity of the soil and air, as well as the thickening of planting. The appearance of bacteriosis can also be associated with a violation of the conditions for keeping cucumber plantings: poor soil, sharp temperature drops, etc.

Gardeners often ignore the rule of agricultural technology, which warns not to grow cucumbers from year to year on the same plot. The infection tends to persist in the soil and infect the plantings of the next seasons.

For the prevention and prevention of bacteriosis, you can spray cucumber lashes with 1% Bordeaux liquid, or 0.4% copper oxychloride suspension. Usually, after such processing, cucumbers begin to tie well and develop.

Improper watering

Cucumbers are very sensitive to watering. They should be watered frequently and regularly, especially during the fruiting period. Do not allow the soil to dry out. However, it is also unacceptable to turn a cucumber ridge into a puddle, this can lead to waterlogging of the soil, and mold and rot are already a stone's throw from it. All this will inevitably lead to the fact that the flowers and ovary begin to turn yellow, rot and fall off.

Watering cucumbers should only be done with warm water: in cool weather - in the daytime, in sunny - early in the morning. On hot days, it is advisable to do refreshing watering (not necessarily to the soil, you can simply sprinkle the leaves), water in the evening as usual. If the ovaries begin to turn yellow (most often this happens in cold, damp weather), carefully remove the flowers and treat these places with a weak solution of potassium permanganate (potassium permanganate).

A large number of ovaries

Do not allow more than 25-30 ovaries to develop on one cucumber lash. Cucumbers grow quickly, especially in a greenhouse, and the plant may not have enough strength for the entire amount of fruits formed. As a result, some interfere with the growth and development of others, and as a result, the gardener has a lot of yellowed and rotten ovaries and the same number of small and crooked cucumbers.

Some varieties of cucumbers, and in particular hybrids, can form up to 150 ovaries on one lash at a time. In order for the harvest to please you, remove the newly formed shoots in time, even those on which there are female flowers.

Lack of trace elements in the soil

A deficiency of trace elements in the soil can also cause yellowing and dropping of flowers and ovaries. At the same time, gardeners lose up to 50% of the cucumber harvest. The lack of trace elements is especially noticeable where mineral fertilizers (nitrogen, potash, phosphorus) are often applied. The situation can be corrected by the introduction of micronutrient fertilizers containing manganese, copper, boron, molybdenum, zinc, etc.

With a large lack of trace elements, it is permissible to use highly concentrated preparations produced by manufacturers in the form of microgranules - Brexil Calcium (Brexil Ca), Rexolin Plus (Rexolin Plus). You can also apply fertilizers "Cristalien", "Terraflex" and "Master" containing NPK - nitrogen-phosphorus-potassium fertilizers with a complex of microelements. Wood ash introduced into the soil in a ratio of 300 g / m2 will help to replenish the deficiency of trace elements.
